HOT-WATER. TANK FOR RANGES.

To all whom it may concern Be it known that I, IVILLIAM V. ROBIN- SON, a citizen of the United States of America, residing at Detroit, in the county of lVayne and State of Michigan, have invented certain new and useful Improvements in Hot-W'ater Tanks for Ranges, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to hot water tanks of the type commonly employed in connection with cooking ranges, and the invention consists in the novel construction as hereinafter set forth.

In the drawings: Figure 1 is a vertical section through the rear portion of the range showing the tank applied thereto. Fig. 2 is a perspective view of the tank removed.

In the construction of ranges provided with hot water tanks, it is usual to pass the gaseous products of combustion around the tank through flues formed by an outer casing. The tanks are usually formed of sheet copper, and where subjected to direct contact with the gases the metal is soon burned out so as to destroy the tank or render it leaky. I have avoided this result by form ing the flue for the gaseous products independent of the tank, and by heating the latter by placing the tank in contact with the flue member to receive heat by conduction.

In detail, A is a portion of the range, having a rear wall B between which and the oven C is formed a flue D for gaseous products.

E is the tank preferably formed of copper which is located in an outer casing F, with one side in contact with the wall B.

It is usual to provide the stove with a marginal rail which overhangs the side, and in the construction shown this rail is formed of the plurality of bars GHI, riveted together. The lower bar G forms a supporting ledge for the upper'flange J of the tank, while the intermediate bar H forms a ledge on which the tank cover may be supported. By reason of the projection of this rail the top of the tank is necessarily spaced from the rear wall B. I therefore form a tank with an inclined upper section K, the front and rear walls of which are parallel and of the same width as the bottom portion of the tank. This permits of inserting the tank through the opening in rear of the rail. When lowered to its seat the inclined por- Speoification of Letters Patent.

tion will force the body of the tank forward until its front side will contact with the rear wall B. To hold the tank in firm contact with the rear wall a wedge bearing L is placed in the outer casing F, which engages the lower end of the tank and will force it against the wall B. The wall B is also preferably braced to hold it in contact with the tank, as by means of a stay M, extending from said rear wall to the oven wall C.

WVith the construction described, the heat conducted through the rear wall B and adj acent contacting wall of the tank will warm the water, while at the same time the tank is protected from the gaseous products of combustion. The outer case F being larger than the tank will form an air jacket, constituting a heat insulation, preventing the cooling of the water by radiation.

l/Vhat I claim as my invention is:

1. In a range, the combination with a wall subjected to the heat and the products of combustion, of a casing projecting outward therefrom and provided with an opening at its top for the insertion of a tank, said opening being spaced from said wall, a tank insertible through said opening having an inclined upper port-ion for forcing the lower portion into contact with said wall, and a wedge bearing for the lower portion of said tank assisting in holding same in contact with said wall.

2. In a range, the combination of a wall of a tank casing extending therefrom, a tank in said casing, and a wedge in the casing for forcing the tank in engagement with the rear wall.

8. In a range, the combination of a wall of a tank casing extending therefrom, a tank in said casing, a wedge member in the cornor of said casing to engage the lower portion of the tank to hold the tank in engagement with the rear wall.

4. In a range, the combination of a wall and overhanging top rail, of a casing adjacent said wall, a tank in said casing, the

front and rear portions of said tank having inclined upper portions, the top of said tank provided with flanges to engage the ledge on the overhanging rail. 7

5. In a range, the combination of a wall, a I

casing extending therefrom, a tank in said casing, the said tank provided with inclined upper portions for forcing the tankin engagement with the wall.

In testimony whereof I aiiiX my signature 1n presence of two wltnesses.
